        Isn't it dark-gray, tho? or as "black" as a dark tube gets,
        rather than "true-black"?

        tHis I'll check out; you've piqued my curiousity, even tho this 
        gets further from whatever I was talking about:-)  ...Not only
        are the psychological varioations, but neurophysiological ones as
        well.  And gender diffs too.  My better two-thirds says that I
        may as well be color-blind, and she's probably right.  What I
        will avoid is having some *Ugly* combos like black on dark blue.
        No, I am Not kidding.  Or yellow typeface on White bg.  It's like
        the shriek/skreek of chalk against a blackboard.  Makes my skin crawl.

        You got me there, man.  I took plenty of psych courses over the
        years, but nothing involving computation.  Congrats.

        Hm. About the only time form/style can top function/contact,
        IMHO, is when you're being forced to watch a very nicely 
        stylized ad.  {On the web.}  I've seen a couple.  O/wise, the way
        a piece works wins.  I listened to an interview on NPR several
        months ago who said that, "I think of people who don't watch web
        advertisement as thieves," or sometime similar.  Isn't a primary
        function of the web to allow *us* to control what we see?

        Sure, but I'll happy leave this niche to people more qualified.
        I'm below the bottom/barrel here.

        i May be off on this one, but I'm seeing more dark grays on my
        ink+paper journals.  Hard to tell since with the years sight
        loses sharpness as our lenses become sclerotic and full of gunk.
        Which all goes back to the original point:: what's the best
        --oh, no-- what *are* the best combinations of off-white and
        darkgray, bluegray, or almost-black-bluegray?

        didn't i mumble something like this above?  25 years ago my eyes
        were much better, but not That much.  i hope someone complained
        ... seriously.
